Custom Animations on 2023

this was my snake animation on minecraft 1.16, im trying to update my mod to minecraft 1.20, but everything changed (again) and all thse animations commands dont work anymore :

public void setRotationAngles(Entity e, float f, float f1, float f2, float f3, float f4) {
			//this.Head.rotateAngleY = f3 / (180F / (float) Math.PI);
			//this.Head.rotateAngleX = f4 / (180F / (float) Math.PI);
			//this.MouthUp.rotateAngleX = f3 / (180F / (float) Math.PI);

			this.Body.rotateAngleY = MathHelper.cos(f * 0.5F) * 0.5F * f1 -0.3491F;
			this.bone0.rotateAngleY = MathHelper.cos(f * 0.5F) * 0.5F * f1 -0.3491F;
			this.bone1.rotateAngleY = MathHelper.cos(f * 0.5F) * 0.5F * f1 -0.3491F;
}
